SODIUM CARBONATE (SODA ASH) Mineral Applications

Applications	Products	Benefits
Glass	soda ash	Particle Size Uniformity - ANSAC's dense soda ash is closely and consistently matched to sand grain size resulting in a homogenous sand/soda ash mix in the glass furnance. This provides predictable, controllable viscosity resulting in a final glass product that is free from distortion.
		Fewer Issues with Soda Ash Fines - Because 97% of ANSAC Dense Soda Ash particles are 75 microns or larger, users will enjoy a more homogenous sand/soda ash mix. This actually saves money since fewer soda ash fines will be blown off and lost during production. In addition, furnace life may be extended since liquid soda ash particles, which dissolve refractories, are minimized in the gas stream. Finally, the narrow distribution of particle sizes, combined with low fines, result in less dusting and easier handling of the product.
		Lower Chloride and Iron Levels - Chloride impurities in soda ash are harmful to the environment and to the life span of the molds and furnaces involved in glass manufacturing. The low chloride values of ANSAC dense soda result in less air pollution. Additionally, by producing lower exhaust temperature during glass manufacture, furnace and mold life is extended. ANSAC dense soda ash also has relatively low levels of iron. This enables glass manufacturers to utilize cheaper, high iron sand while continuing to produce a glass that meets their standards for clarity.
Detergents and soaps	soda ash	The addition of soda ash prevents hard water from bonding with detergent, allowing for a more even distribution of the cleaning agent during the washing cycle. Soda ash is also very effective in removing alcohol and grease stains from clothing.
Chemicals	soda ash	Soda ash is an acknowledged source of sodium ions. It also aides the solubility and reactivity of many inorganic compounds in water. As such, it is used as a major raw material for the economical production of sodium phosphates, sodium silicates, chrome chemicals and photographic chemicals. It is also used in the production of sodium bicarbonate (baking soda), which is an essential ingredient in the beverage, coatings, detergents, food, dialysis, and personal care markets.
